The sport of cheese racing began in 1997 when a group of friends put individually-wrapped cheese slices onto a barbecue grill to see what would happen. To their surprise, the plastic did not melt or burn. But the cheese expanded, turning the objects into inflated pillows! The object of cheese racing is to see whose slice reaches full inflation first.
